Determining the proper corn plant population

One factor that greatly influences corn yields is plant population. Determining the correct plant population may take some effort, however, it is a critical factor that every corn grower needs to get right in order to maximize yields. Recent research performed by universities and seed companies has determined that that yields increase significantly as populations are increased up to a point of 34,000 seeds per acre. In general, yields begin to level off at planting rates around rates 36,000 seeds per acre. Recent studies have also determined that even in low yield environments planting rates of 31,000 seeds per acre maximize yield and economic return. In very productive, 250 bushels per acre yield environments, research results show that higher populations (38,000+ seeds per acre) maximize yields. Breeding and advances in genetics have improved the modern corn plant’s ability to yield at higher populations when compared to corn hybrids from the past.… Continue reading
